Interoperability
An advanced weapon and space systems company
1. Ammunition meets the requirements of NATO STANAG 4385
– Designed, tested and manufactured to this standard from beginning.
– Interoperability is maintained by the Interface Control Document
(ICD)
– ICD is maintained by International Joint Configuration Board
2. Ammunition interoperability is demonstrated when fired from the compatible platform.

Purpose for Test Firing US Ammunition in Leopard 2 Tanks
An advanced weapon and space systems company
Purpose of test firing 1. Support NATO Allies for deployment in Afghanistan 2. Demonstrate the interoperability of US ammunition in the Leopard 2 tank with L44 and L55 weapon system
– M865 and M831A1 training ammunition is already used by countries with Leopard 2 tanks
3. Check ammunition performance across temperature and distance using the existing Leopard 2 firing control
4. Demonstrate functional performance against targets when fired from the L44 and L55 weapon system
Demonstrate the interoperability in the Leopard 2 Tanks

How We Arranged the Demonstration Test
An advanced weapon and space systems company
• The Danish Army hosted the event in Oksboel Training Center
– Provided the test range, targets, Leopard 2/A5 MBT, test crew and instrumentation, facilities and transportation on site, and focal point for logistics.
• The Dutch Army provided the Leopard 2/A6 MBT, test crew and instrumentation, and assisted in coordination and logistics
• The ammunition producers, ATK and GD-OTS, provided the ammunition and assisted in logistics and support.
• US Army provided on site support at the test
The Demonstration Test took several months of planning. As cooperation and enthusiasm grew we decided to invite other 120 user nations to witness the test.
12 Countries were able to attend the test.

M1002 MPTP-T Training Round NSN 1315-01-509-3555
An advanced weapon and space systems company
Test Fired 20 rounds to verify fire control across temperatures: • 6 from each tank at temperature -32C, +21C, +50C tracking projectile to tank fire control • 4 from each tank using the existing Leopard 2 tank Ballistic setting, A2 of fire control system, at
+21C for zeroing on a target at 1,000m measured for precision
• Results (H X V mils) L44 = 0.14 X 0.22 , L55 = 0.20 x 0.03
Results showed ammunition works well in Leopard 2 Tank System
2 rounds went through the same hole
